What started as a simple ticket ended up reaching the way up to the
MPI Forum.
It turns out that we are supposed to have MPI_SIZEOF for all Fortran
interfaces: mpif.h, the mpi module, and the mpi_f08 module.
It further turns out that to properly support MPI_SIZEOF, your Fortran
compiler *has* support the INTERFACE keyword and ISO_FORTRAN_ENV. We
can't use "ignore TKR" functionality, because the whole point of
MPI_SIZEOF is that the implementation knows what type was passed to it
("ignore TKR" functionality, by definition, throws that information
away). Hence, we have to have an MPI_SIZEOF interface+implementation
for all intrinsic types, kinds, and ranks.
This commit therefore adds a perl script that generates both the
interfaces and implementations for MPI_SIZEOF in each of mpif.h, the
mpi module, and mpi_f08 module (yay consolidation!).
The perl script uses the results of some new configure tests:
* check if the Fortran compiler supports the INTERFACE keyword
* check if the Fortran compiler supports ISO_FORTRAN_ENV
* find the max array rank (i.e., dimension) that the compiler supports
If the Fortran compiler supports both INTERFACE and ISO_FORTRAN_ENV,
then we'll build the MPI_SIZEOF interfaces. If not, we'll skip
MPI_SIZEOF in mpif.h and the mpi module. Note that we won't build the
mpi_f08 module -- to include the MPI_SIZEOF interfaces -- if the
Fortran compiler doesn't support INTERFACE, ISO_FORTRAN_ENV, and a
whole bunch of ther modern Fortran stuff.
Since MPI_SIZEOF interfaces are now generated by the perl script, this
commit also removes all the old MPI_SIZEOF implementations (which were
laden with a zillion #if blocks).
